fromautomatic controllingand circuit breaking systems) using an internalcombustion. or explosive engine as a prime motive power in connectionwith a suitable electro-magnetic machine and an electric storage batteryor accumulator.

The objects of my invention are not only to provide means for charging-the\battery (the current from which may be used for any purpose) but tomake this means entirely automatic in its operation; also to emloy noother prime units to obtain this result other than the units of theplant, viz: the explosive motor, the electro-lmignctic machine and theelectric storage battery; in other words, to make the above units automatic in their operation and able to care for themselves, without theassistance of an attendant, starting, of course, 'with the battery atleast artially charged;

A furt ier object is to provide an arrangement wherein the battery isalways connected to the circuit in the building where the current is tobe used.

In connection with the above mentioned prime units, I provide suitableinstruments, preferably in the form of ampere hour meters, the operationof which will be dependent on the amount of electricit and the directionof its flow through t e metersto control the starting and stopping ofthe prime motive power. p

This system must not be confounded with systems Avherein the explosiveengine is started by a person and the dynamo started and -stopped atsuitable times or connected and disconnected with, the battery atsuitable times, for, in my present system the means for charging thebattery and the bat tery itself are utilized as means'for starting -theengine to charge the battery. The igni- ,tion circuit to the explosiveengine is also controlled by the instruments which control the mamcircuit between the battery and the dynamo after a certain predeter-.

mined amount of electricity has passed through the instruments 111either direction. I also provlde means for keeping the compression ofthe engine cylin'der released un- ;-.t1l its momentum 1s sufiic-ient tocarry it past the compression oint.

A further ob ect is to provide means whereby the said electric storagebattery is prevented from discharging below a certain predeterminedpoint without starting the engine and dynamo-to replenish the batteryand to automatically stop said engine .when a certain predeterminedamount of electricity has passed into the battery.

The invention is more fully described in the following specification andclearly illustrated .in the accompanying drawing, in which Figure l is adiagram of my system. Fig. 2 shows the compression releasing apparatusfor the engine.

The numeral 1 designates the explosive engine: 2 is the electro-magneticmachine; 3

the storage battery; 4 and 4f represent ampore hour meters; 5 and 5 themagnets: 6 is theignition coiland 7 the lights or equivalent.

Assuming that a certain predetermined amount of electricity has passedfrom the battery to the circuits where the current is to be-used, theneedle 8 on the meter 4 will, when this amount has passed through it,contact with'the terminus 9 and ener ize the magnet 5 by closing thecircuit leading from the battery tosaid ma net through the meter,- andthis action wil cause the said magnet to draw toward it the pivoted arm10. This arm is provided with a spring 11 so placed that it willkeep thearm in either position placed by the magnets. \Vhen this armmovesytoward the magnet 5" the free end will contact witlrthe terminals12 of the. main circuit and close said circuit} simultaneously with saidaction, the arm willalso contact with the terminal 13 of the ignitioncircuit and produce the initial spark in the combustion chamber; of theengine to which it is connected at the spark plug 14. It will be seenthat in thismanner the electro-magnetic machine will first operate as amotor, and inasmuch as it is connected by a belt 15 with the engine, itwill start the said engine and permit 1t to draw a charge and begin itsaction. Nhen the engine has thus been started, it in turn will givemotion to the electro-
